QPPX Programmable Transducer

QPPX Programmable Transducer, an AC programmable transducer, measures a wide range of electrical parameters and generates analog or digital output signals suitable for interfacing with instrumentation and control systems. It has total four channel output, with panel key or PC control programmable. User can free to set 4 different data from max 26 electrical parameter for sampling and analog signal output.

The programmable transducer has three channel digital inputs and RS485-Modbus communication functionality. Can monitor the galvanically isolated DI signal and programmed the transducer with customized SCADA software, any of the measured parameters can be read out via the RS485 connection.
